Abstract
Official abstract text for this publication.
A piezoelectric vibrator element includes a vibrating portion that excites thickness-shear vibration, and a peripheral portion that is disposed on the periphery of the vibrating portion and has a thickness thinner than the vibrating portion, the vibrating portion and the peripheral portion being formed in a piezoelectric substrate. A buffering portion and a mount portion are sequentially connected to the peripheral portion. The buffering portion includes a slit formed between the mount portion and the peripheral portion. The mount portion has notches which are formed at both end portions in a direction orthogonal to an arrangement direction of the mount portion, the buffering portion, and the peripheral portion.
First claim
Opening claim text (preview).
What is claimed is: 1. A piezoelectric vibrator element comprising: a vibrating member that is in a rectangular shape with first through fourth sides, a peripheral portion that is continuously formed at the first through third sides in a peripheral area of the vibrating member, a vibrating portion that is formed at a center area of the vibrating member and that is surrounded by the peripheral portion; a neck portion, a buffering portion and a mount portion that are sequentially…
